Warriors star point guard Stephen Curry has decided to leave Nike and sign a new deal with the up-and-coming brand Under Armour, according to multiple sources.

Curry will debut is new allegiance at the Warriors’ media day on Friday.

His contract with Nike expires at the end of September. His rising stardom, coming off the Warriors’ playoff run, prompted Under Armour to go hard after Curry. After months of negotiations with both companies, Curry made the surprising move to leave the shoe giant, who he signed with as a rookie, to become the face of the new kid on the block.
